In the lead-up to the NATO summit in Chicago from May 20 - 21, the city has acquired 500 troopers from the Illinois State Police as well as 600 Illinois National Guard troops for the summit and accompanying protests. What protesters still don't know is the location restrictions that the Secret Service will enforce on protest areas, prompting concern from the ACLU.

The Chicago Sun-Times reports today that City Hall sources gave the information on hundreds of additional Illinois State troopers on Friday, while the Illinois National Guard disclosed its information on hundreds of guards for support earlier this week.

The ACLU has been demanding information on security perimeters for the summit to ensure “effective exercise of First Amendment expressive activities.”
